Elevation one way out of flood zone

Given it is hurricane season, it is appropriate to ask whether Rhode Islanders are any safer from a hurricane today than they were three years ago when Hurricane Sandy hit.

The answer is probably “somewhat safer,” given the efforts of federal, state and local governments at public education and hazard mitigation.

But three years is not a lot of time, and significant change takes time.

However, perhaps there are some simple things that can be done.

One may be to require municipalities to allow those building in flood hazard areas to claim an extra margin of safety if they so choose.

For example, currently the state building code requires 1 foot of “freeboard,” being the minimum distance above base flood elevation that the lowest floor of a structure, or the lowest horizontal structural members, may be built.

Base flood elevation is measured by the flood level expected in a severe storm, known as a 100-year flood.

There have been efforts to require a greater freeboard, such as 2 feet. This has been opposed by some because it is unnecessary, or would block neighbors’ water views or make access difficult for the elderly.

Given recent federal legislation, flood insurance premiums, subsidized by the federal government for decades, are being allowed to rise gradually to true actuarial value. That means flood insurance premiums will significantly increase over the years, and homes in flood zones could see annual insurance premiums that look more like annual mortgage payments.

That may make the house unaffordable for the current owners, and it may mean that when it is put on the market for sale, its purchase price may be reduced by tens of thousands of dollars.

Either would be disastrous for the average family.

Some municipalities allow homeowners to elevate their existing home, or build their new home, several feet above the base flood elevation.

Rather than requiring elevated construction, perhaps the General Assembly could require all municipalities to allow homeowners who so choose to elevate or construct their home up to 5 feet above base flood elevation.

Another thought is to make low-interest or no-interest state or federal funding available for those who want to undertake elevating existing homes to move out of, or further out of, the flood zone. Some federal money is being used for this now in Rhode Island.

Both approaches avoid a government mandate and put the decision on the property owner. •
